SLICING BTACHNE.

Application fried :my 30, 1924. serial No. 728,993.

To all whomz't may concern:

Be it known that l, Soncino-N l/ViLm a citizen of the "United States, and resident of tochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Slicing h/lachines, of which the following is a specification.

The present invention relates to slicing machines and more particularly to the type in which acutter is mounted on a main frame and acarriage reciprocates back and forth past the (Hitting edge of the cutter and carries a meat table which is advanced toward the plane of operation of the cutter upon each back and forth movement of the carrier. rin object of this invention is to provide an improved locking means which will lock the meat table against movement either in a retrogrfule direction or in an ad vancing direction, while, at the same time, will permit the advancing of the table through the medium of a step by step advan c in g mechanism.

To this and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described; the novel features being pointed out in the appended claims.

ln, the drawings:

Fig. 1 is a plan view of a slicing machine constructed in accordance with this invention;

Fig. 2 is an enlarged plan view of the table and carriage broken away to illustrate the operating parts;

l? 5% is a view similar to F ig. 2, showing the locking device out of locking relation with the toothed member;

Fig. 4l, is a section on the line Lil-t, Fig. 3; and

Fig. is a section on the line 5 5, Fig. 3.

in the iliiistrated embodiment, 1 indicates the main frame of the machine which has a rotary cutter 2 mounted to turn thereon through the medium of a crank disk, this crank disk being also connected to a carringe l for imparting to the carriage a reciprecating or back and forth movement past the edge of the cutter. Gn the carriage 2 is a meat table 5 which through guides 6 is movable transversely of the line of movement of the carriage l toward and from the plane of operation of the cutter 2, all of which is not fully shown herein but is old in the prior art. A materia-l clamp 7 of any suitable construction is arranged on the meat table 5 to secure the material against movement on the table.

l/lovement of the table 5 on the carriage 4l is effected preferably through a rack bar t3, in this instance, pivoted at 9 to the un.- dersde of the. table 5 and extending` beyond one side of the table to provide a finger piece l0 by which the rack 8 may be moved on its pivot 9, a latch 11 holding the rack normally in operative position. Cooperating with this rack is a pinion 12 which is rigidly secured to a stub shaft 13 mounted to turn in a strap la which is by 'bolts 'l5 secured to the underside of the carriage t, the carriage having an opening 16 through which the shaft 13 extends in order that the pinion 12 may lie above Athe carriage 4 and cooperate with the rack 8. Rigidly secured to the shaft 13 is a ratchet wheel or toothed member 17. `ltfovement of `this ratchet or toothed member 17 may be effected by a swinging member 1S mounted to turn betweenA its ends on the shaft 13 and having on one side of its pivot a spring 19 connect-ed thereto at one end, the 'other' end of the spring being anchored at 2O to the underside of the carriage l. The spring normally holds the member 18 against the stop 24 on the carriage 4e. On the opposite side of the pivot of the swinging member 18 the latter carries an advancing pawl 21 whichis. piV- oted at 22.to said member 18 and is held normally in vengagement with the toothed member 17 b-y a spring 23. Arranged on the main frame 1 is a stop or abutment 24:a which, as the carriage 4 approaches: the eXtreme end of i-ts return movement before its movement in advancing toward the knife to produce the cutting, is engaged by the lug 18a the swinging mem-ber 18 and shifts the latter on its :pivot tovcause the advancing pawl 21 to shift the toothed or ratchet wheel 17 and turn the gear 12., thereby shifting the table 5 one step. ltfoveme-nt of the table in the opposite direction may be effected by releasing the rack bar 8 from the latch 11 so that the rack bar may be swung on its pivot 9 in order to be disengaged from the gear 12, thereby permitting the table 5 to be moved away from the knife or toward the knife by a quick movement.

The locking mechanism embodies prefenably a toothed member 25, in this instance, in the form of a disk or wheel secured to the shaft 13 to turn therewith. This toothed member has the notches between its teeth V shaped and in these notches the V shaped end 2G of a locking detent is adapted to engage. This loching detent, in this instance, is slidablv mounted in guides 28 and is moved toward the toothed member 25 by a coil spring 29 secured at one end at 3G to the detent and the other end at 31 to one. of the guides 8. Vthis detent is operated away from the locking member just prior to the time that the carriage 5 is shifted through the advancing pawl 21 and immediately reengages the toothed member 25 after the shifting. This result, in this instance, is effected by shifting the pawl pivoted between its ends at to a swinging member 34, that is, in turn, pivoted at 35 to the under side of the carriage 4. The shifting pawl has a nose whic-i is adapted to enter a notch 37 in the detent 27 to engage one wall of the notch in order to shift the detent 27 away from the toothed member 25. rl`he detent 32 also has a bevelled portion which is adapted to cooperate with a i'iXed abutment after the shifting detent 32 has been moved a certain distance.

As the carriage 4 approaches the end of its return movement and before the swinging member 18 engages the stop or abutment 24, the swinging member 34 strikes an inclined abutting surface 40 on the main frame l and shifts the swinging member 34 on its pivot 35, thereby causing the nose 36 of the shifting pawl 32 to shift the detent 27 out of engagement with the toothed. member 25. Thereafter the swinging member 18 engages the abutment 24a and shifts the advancing pawl 21 sc as to advance the carriage 5 toward the knife. Vhile this advancing is taking place, the swinging member 34 travels on the surface 41, so as to hold the detent 27 out of engagement with the toothed member 25, until the return movement is just about completed when the swinging member 34 engages an abutting surface 42 and is moved still further on its pivot, thus bringing the inclined surface 38 on the shifting detent 32 in engagement with the abutment 29 in such a manner as t-o shift the shifting pawl 32 on its pivot 33 out of fngagement with the detent 27, thus freeing the detent 27 to the action of its spring 29 and permitting the nose of the detent to interlock with the toothed wheel 2,5. At this time, the carriage has completed its return movement and the advancing pawl 21 has completed its movement so that the latter under the action of the spring 17 returns to normal position as the carriage advances again toward the knife on the cutting movement.

From the foregoing it will be seen that there has been provided a slicing machine in which there is a locking mechanism of novel construction holding the meat table Laaaeae against movement on the carriage either toward the knife or cutting mechanism or away from such mechanism during the movement of the carriage back and forth past the cutting mechanism except when the table advancing mechanism is brought into operation. This result is accomplished by providing a toothed member moving with the table and having a locking detent engaging therewith, such detent holding the toothed member against movement in either of two directions and being moved out of cooperation with the toothed member just prior to the operation of the table advancing mechanism, and such detent being immediately released after the advancing movement of the table. The locking detent is preferably controlled by a means operated by a part on the frame and first shifting the locking detent away from locking position and thereafter releasing such detent to permit it to move into locking relation with the toothed member. In the illustrated embodiment, a swinging member on the carriage has a shifting detent pivotally mounted thereon and cooperating with the locking detent to shift the latter out of cooperation with the toothed member. Means also cooperates with the shifting detent to break its connect-ion with the locking detent in order to permit the locking detent to move to locking position.
